ELI5: Explain Like I'm 5

Multiplier (Fourier analysis)

Okay, kiddo, imagine you have a magic way of looking at how things are made of different parts. It's like breaking a toy apart and seeing all of its pieces. But instead of physical pieces, you can see how things are made up of different kinds of waves.

A multiplier in Fourier analysis is a magic tool that helps you see which parts of waves are working together to make something bigger or smaller. It's like putting a toy back together, but this time you can see which pieces are sticking together tightly and which ones are just hanging out.

This tool is really useful if you want to study how music is made, or how pictures and videos are made out of pixels. By using a multiplier, you can see which waves are important to make your favorite songs or show your favorite movies.

So, the multiplier is like a special tool that helps us understand how different waves are put together to create something we can see or listen to.
